Course Introduction：PHP algorithm design ideas: How to achieve an efficient solution to the topological sorting problem? Topological sorting is a classic problem in graph theory. Its main goal is to sort a directed acyclic graph (DAG) so that all vertices in the graph satisfy the condition that the in-degree is less than or equal to the out-degree. Topological sorting is widely used in many scenarios, such as task scheduling, compiler design, etc. In this article, an efficient solution for topological sorting using PHP language will be introduced. First, we will discuss the basic principles of topological sorting algorithm, and then give specific codes.

Course Introduction：How to use Java to implement topological sorting algorithm Topological sorting is a commonly used algorithm in graph theory, used to sort the vertices of a Directed Acyclic Graph (DAG for short). Topological sorting can be used to solve problems such as dependencies or task scheduling. In this article, we will introduce how to use Java to implement the topological sorting algorithm and give corresponding code examples. The implementation idea of ​​topological sorting is as follows: First, we need to define a data structure of a directed graph, which can be done using an adjacency list.

Course Introduction：Method: 1. Find a node in the graph with an in-degree of 0, remove this node from the graph and add it to the sequence E; 2. Remove all edges associated with the node found in 1 from the graph; 3. Repeat steps 1 and 2 until all nodes in the graph are removed or a node with an in-degree of 0 cannot be found.

Course Introduction：How to write a topological sorting algorithm using PHP Topological sorting is an algorithm for sorting directed acyclic graphs (DAGs). Its principle is to sort the nodes in the graph according to dependencies to ensure that the directions of all edges in the sorting results are consistent. In actual development, topological sorting is often used to solve problems such as task scheduling and dependency analysis. This article will introduce how to write a topological sorting algorithm using PHP, with code examples. Algorithm idea: Create an in-degree array to save the in-degree of each node (that is, how many nodes point to this node
